Description

  The present invention relates to a photographic illumination device used for taking a photograph, and more particularly to a photographic illumination device that can easily take a good photograph using stationary light close to natural light.

Conventionally, when taking a photograph of a person at a studio location in a photography studio, a strobe device is used for almost all of the lighting devices, and a discharge lamp or the like is used as a strobe light source to perform flashing operation. A photograph is taken (see, for example, Patent Document 1 below).
JP 2003-177461 A

  However, when taking a picture with a strobe device as a light source indoors, it is necessary to increase the light emitting area of the lighting device in order to reduce the shadowing of the subject, but for this purpose, a large strobe is used. Like the main strobe, front strobe, and top strobe, there were problems such as the need to install many.

  Also, in the case of strobe shooting, unlike with shooting with steady light, it is not possible to adjust the aperture or shutter speed of the camera by measuring the illuminance of the light actually irradiated to the subject. The camera's aperture and shutter speed are adjusted in anticipation of the amount of light emitted from the flash device that lights up in synchronization. For this reason, when a plurality of strobes are used, there is a problem that it is difficult to accurately adjust the aperture and shutter speed of the camera without performing test shooting.

  Conversely, the flash start time and flash end time of the strobe device are controlled according to the preset aperture and shutter speed of the camera, such as the main strobe, front strobe, and top strobe. There is a problem that it is difficult to accurately control the light emission times of a plurality of strobes according to the aperture and shutter speed of the camera, and it is difficult to take a good picture without taking a test picture.

  The present invention solves the above-described problems, and an object of the present invention is to provide a photographic illumination device that can easily shoot a photograph with good color tone using stationary light.

  The illuminating device for photography according to the present invention is a photographic illumination device used when performing studio location photography of a still photo in a studio, and has a color temperature approximating natural light on the ceiling in the photography studio. A ceiling fluorescent lamp that emits steady light is arranged, a main spotlight that irradiates the subject with steady light is arranged approximately in front of the subject in the photography studio, and a backlight that illuminates the back wall with steady light A top spotlight is provided above the subject to irradiate the subject with steady light from above the subject, and an upper spotlight is provided to irradiate the subject with steady light from diagonally forward and lower sides of the subject. It is characterized by that.

  Here, in the lighting device, in addition to the ceiling fluorescent lamp and the spotlight, a front spotlight that irradiates the subject with steady light from the front in front of the subject can move in the studio. It can be set as the structure attached on the movable stand arrange | positioned in (1).

  In addition, as described in claim 3, a Fresnel lens spotlight using a Fresnel lens can be used for the main spotlight, the backlight, the top spotlight, the upper spotlight, and the front spotlight.

  Further, as described in claim 4, a backlight light for irradiating steady light from the back side of the subject can be provided on the back side of the subject.

  Further, as in claim 5, the ceiling fluorescent lamp, the main spotlight, the backlight, the top spotlight, the upper spotlight, the front spotlight, and the backlighting light are connected to a dimming control panel, and the dimming control A plurality of scene data composed of a light to be used and its light amount data is stored in advance on the board, and the light control of each light can be performed based on the scene data.

  The photo illuminator having the above structure is installed in a studio for taking a still photo in a studio location, and the ceiling fluorescent lamp, main spotlight, top spotlight, upper spotlight, and front spotlight are all or selected. It is used by turning on the lit lamp. A camera installed in front of the subject in such a state that the steady light is emitted from the lamps toward the subject, and the steady light is emitted from the backlight toward the back seat. Photography is performed.

  Steady fluorescent light similar to natural light is emitted from the ceiling fluorescent lamp as basic illumination to the entire studio including the subject, and is constantly directed toward the subject from the main spotlight, top spotlight, upper spotlight, and front spotlight. It is possible to illuminate the subject with a sufficient amount of light and almost no shadow. In addition, since the illuminated subject can be photographed while looking at the camera's viewfinder, the automatic iris adjustment function or the automatic shutter speed adjustment function can be operated, or the illuminance of the subject can be accurately measured using an illuminometer. The aperture and shutter speed of the camera can be set according to the measurement and the illuminance, and even a inexperienced photographer can take a good picture.

  Further, a fluorescent lamp that irradiates steady light that approximates natural light having a color temperature of 5500 ° k, for example, is used for the ceiling fluorescent lamp, and a color temperature that is close to natural light, such as a metal halide lamp having a color temperature of 5600 ° k, is used for the spotlight. If you use a spotlight with a soft edge light that emits soft edge light while using a lamp that radiates the light, you can illuminate the subject with flood light that is close to natural light and shoot with natural light You can take beautiful pictures with the same natural colors as you did.

  In addition, the main spotlight, upper spotlight, and front spotlight irradiate the subject at a relatively close distance with the steady light from the ceiling fluorescent lamp as basic lighting, so the efficiency is reduced with a small number of lamps. It can be well lit, and can be used economically with small power supply facilities and power capacity, unlike lighting equipment that uses many light groups such as television studio lighting equipment or stage lighting.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 and FIG. 2 are layout diagrams of a photographic illumination device used when performing studio location shooting of a still photo in a photo studio.

  A ceiling fluorescent lamp 6 is attached to the ceiling of the photography studio as basic lighting equipment. The ceiling fluorescent lamp 6 is equipped with a plurality of fluorescent lamps 6a that irradiate light having a color temperature of 5500 ° k that is very close to natural light. This fluorescent lamp 6a is a lamp that emits light having a spectral spectrum in the visible light region substantially the same as natural light. The length and number of fluorescent lamps 6a to be used can be arbitrarily determined, but are basic illumination. The length and number of the fluorescent lamps 6a are determined to such an extent that the illuminance sufficient for photographing (illuminance on the floor of the studio is, for example, 5000 lx to 10000 lx) can be obtained with the ceiling fluorescent lamp 6 alone. In front of the back wall, the back sheet 9 is disposed so as to be pulled out from above to the floor, and a subject such as a person is disposed in the front center of the back sheet 9.

  The main spotlight 1 is attached to the ceiling portion of the photography studio so as to be directed obliquely forward and downward so as to irradiate the light toward the subject. In addition, two backlights 5 are arranged on the floor with the back wall facing, and are installed so as to irradiate the back sheet 9 with steady light. The top spotlight 2 is attached to a ceiling portion directly above the subject so as to irradiate the subject with steady light from above the subject.

  Further, the upper spotlight 4 is disposed obliquely in front of the subject and disposed so as to irradiate the subject with steady light from the obliquely lower front side of the subject. In addition, the front spotlight 3 is arranged on a moving table (not shown) so as to irradiate the light from the front side of the subject, and is arranged with the subject facing substantially in front of the subject. The front spotlight 3 is disposed so as to be movable in the studio by moving a moving table, and can be moved to an arbitrary position. The front spotlight 3 can also be used as a backlight light by being installed on the back side of the subject.

  For the main spotlight 1, the backlight 5, the top spotlight 2, the upper spotlight 4, and the front spotlight 3, for example, spotlights using incandescent bulbs, xenon lamps, halogen lamps or the like of 100 W to 500 W should be used. For example, a lamp that emits steady light having a color temperature close to natural light, such as a metal halide lamp having a color temperature of 5600 ° K, can be used.

  Further, as the main spotlight 1, the top spotlight 2, the upper spotlight 4, and the front spotlight 3, a Fresnel lens spotlight using a Fresnel lens is used. The Fresnel lens spotlight has a characteristic of creating a soft edge light with a soft outline of an irradiation surface, and can irradiate a so-called floodlight on a subject. When irradiating a subject with steady light of a narrowed luminous flux having directivity such as direct sunlight, a normal spotlight using a normal plano-convex lens is used.

  The steady light from the ceiling fluorescent lamp 6 which is the basic lighting equipment can secure the illuminance of the entire studio and the distance between the light and the subject is relatively short. Compared to the lighting equipment of, the lighting device can be configured with a much smaller number of lights.

  The main spotlight 1, the backlight 5, the top spotlight 2, the upper spotlight 4, the front spotlight 3, and the ceiling fluorescent lamp 6 are connected to a dimming control unit 11 of the dimming panel as shown in FIG. Dimmed. The dimming board is provided with a dimming storage control unit 12 for controlling the dimming control unit 11, and the dimming storage control unit 12 is connected to an input operation unit 13 for operation by a user. The dimming storage control unit 12 includes a CPU, a RAM, a ROM, an input / output circuit, a storage device, and the like, and a plurality of scene data including a light to be used and its light intensity data is stored in the storage device in advance. . During the lighting operation, scene data designated according to the operation of the input operation unit 13 is read from the storage device, and dimming control of each light is performed based on the scene data.

  As the scene data, for example, when the scene title is “morning”, the ceiling fluorescent lamp 6 is set to irradiate with the luminous intensity 5, the main spotlight 1 with the luminous intensity 6, and the front spotlight 3 with the luminous intensity 4. When the scene title is “night”, the ceiling fluorescent lamp 6 is set to irradiate with the luminous intensity 1, the main spotlight 1 with the luminous intensity 3, and the front spotlight 3 with the luminous intensity 3.

  The dimming control unit 11 is provided with a thyristor control circuit that performs chopper control of the power supply voltage or current supplied to each spotlight, and a phase control circuit that performs dimming of the ceiling fluorescent lamp 6. By adjusting the arc angle or controlling the phase of the AC power supply, the power supplied to each spotlight and the fluorescent lamp of the ceiling fluorescent lamp 6 is controlled to adjust the luminous intensity (luminance) of the lamp.

  Depending on the shooting scene of the studio location, there may be a case where a shooting location facility (for example, a wall on a street corner) is installed on the wall portion in the studio without using the back sheet 6, in which case the wall surface of the facility An indirect illumination light can be attached to the inside of the lamp so that indirect light is emitted from a window on the wall surface.

  The photographic illumination device configured as described above is installed and used in a studio as shown in FIGS. 1 and 2 when taking a still photo in a studio. A digital camera is used as the photographic camera 10 and is installed approximately in front of the front of the subject.

  The lighting device is operated by designating a preset scene by operating the input operation unit 13 of the dimming control panel or by designating a light to be operated and its intensity by operating the operation unit. At this time, for example, when the ceiling fluorescent lamp 6, the main spotlight 1, the top spotlight 2, the upper spotlight 4, the front spotlight 3, and the backlight 5 are used, their light amounts are controlled by the dimming control panel, The ceiling fluorescent lamp 6, each of the spotlights 1 to 4 and the backlight 5 are controlled to the light intensity set by the dimming control unit 11.

  The fluorescent lamp 6a of the ceiling fluorescent lamp 6 irradiates substantially the entire photo studio with steady light having a color temperature of 5500 ° k, which approximates natural light as basic illumination, and each spotlight 1 to 4 is directed toward the subject. Steady light is irradiated and the steady light is irradiated from the backlight 5 toward the back sheet 6. The subject in the studio is irradiated with the steady light having the light intensity adjusted as described above, and in this state, a photograph is taken by the photography camera 10 installed in front of the subject.

  During shooting, the ceiling fluorescent lamp 6 irradiates the entire studio with steady light having a color temperature approximating that of natural light, and each spotlight 1 to 4 also has a color close to natural light, such as a metal halide lamp having a color temperature of 5600 ° k. When a lamp that emits constant temperature light is used and a Fresnel lens that emits soft edge light with a soft outline of the irradiated surface is used, flood light close to natural light is irradiated onto the subject. For this reason, a beautiful photograph can be taken by soft edge illumination with a natural hue similar to that obtained by natural light and a soft outline.

  On the other hand, when illuminating a subject with a strong shadow by using highly directional spot illumination, the luminous intensity of the ceiling fluorescent lamp 6 for basic illumination is lowered, and a plano-convex lens spotlight is used for the spotlights 1 to 4. If a light is illuminated, it is possible to take a photograph with a high effect of light.

  In this case as well, at the time of shooting, it is possible to shoot the state of the subject illuminated by the steady light while looking at the viewfinder of the photographic camera 10, so the automatic aperture adjustment function or the automatic shutter speed adjustment function is operated, Alternatively, the illuminance of the subject can be accurately measured with an illuminometer and the aperture and shutter speed of the camera 10 can be set according to the illuminance, so that even an inexperienced photographer can take a good picture. it can.

  Further, since the main spotlight 1, the upper spotlight 4, and the front spotlight 3 are used to illuminate the subject together with the ceiling fluorescent lamp 6 that emits natural light, the illumination can be efficiently performed with a relatively small number of lights. Unlike a lighting device using a large number of light groups such as a lighting facility of a television studio or stage lighting, it can be used economically with a small power supply facility and power supply capacity.
